Sink or swim

Long story short we are being put on mandatory 10&12 hour shifts next month. I personally am in favor along with the majority of my coworkers . The rest are mad about it but it's either you do it or find another job in the words of the powers that be. Anyway 2 regular night nurses are literally showing their butts over the schedule.one wants an extra shift but also wants more time off and nobody else will switch because they like their schedules. The other one comes out with more hours and less days but wants more time off both have 4 & 5 days off in a row. This is the first time they've not been able to get whatever they want & they are mad. One of them is not a team player at all & can barely stand on his own feet but is used to others picking up his slack. I don't see what the fuss is about. I'm thankful to have a job. However I'll be stuck with him a few times and I will not pick his slack up. I've carried a 3 ton load on my back for 2 years now. I want a pleasureable work environment with out the chaos & drama I've put up with for so long. I'm surprised at how undermining and sneaky they are being . They've been trying to take shifts from others without permission which so far hasn't been sucessful. They've even been hiding report sheets from us. Wha grade is this ???? Neither nurse has ever come in on any shift when we've been short and they won't ever answer the phone or return calls when we need help yet they want to take someone elses hours? It's like the guy nurse wants a free paycheck! Plus they don't know the hs med passes but they'd be more in tune if they'd have came in once in a while to help out for 4 hours. It's heavy but not impossible. My ? Is this: how does a team oriented person make do with working with non team players? Is it a recipe for failure? How can you cope with slackers in a nonjudgemental fashion without blowing your top at some point? I was originally supposed to work with this guy 32 hours in a week but I told the don I couldn't be with him that many. My head would surely explode after a month or two of that so she switched it around why do people have to dramatize change before giving it a try?
